Cloud computing essay example
Still, a developer sees an operating system interface, and so viewing it in this light makes more sense here.
A mapping service such as Google Earth is just as clearly application-centric—only certain kinds of apps need it—as is a service like Live Search. This typically includes various support functions, such as standard libraries and storage, and a base operating system.
The other customer is an internal customer so the company spends capital to either provide services and data internally, or spends capital to provide the servers, storage, networking, and applications capital spending for an external customer.
Integration: Connecting applications within an organization usually depends on a remote service provided by some integration product.
Similarly, SaaS applications today frequently expose services that can be accessed by on-premises applications or by other cloud applications. When talking about a cloud computing system, it's helpful to divide it into two sections: the front end and the back end.
References Armbrust, M. Cloud computing comprises following two levels: ' front end users: customers or users using those service on their device ' back end users: service provider or vendor managing the services Part of the confusion in cloud computing is that there are two completely different customers for two different types of clouds.

That is, cloud computing is a hardware and software that is available to the user via the Internet or LAN as a service, allowing the use of web-based interface for remote access to the allocation of resources computing resources, programs and data. An identity service in the cloud can address these issues. Identity Whether an application runs on-premises or in the cloud, it typically needs to know something about its users. Commercial offerings need to meet the quality of service requirements of customers and typically offer service level agreements, Open standards and open source software are also critical to the growth of cloud computing. The other customer is an internal customer so the company spends capital to either provide services and data internally, or spends capital to provide the servers, storage, networking, and applications capital spending for an external customer.

Agility improves with users' ability to re-provision technological infrastructure resources. The value of cloud computing is extensive, especially considering the mobility agenda of the modern generation and the capabilities and expectations associated with new mobile technologies CCAS, While the old world does not go away, a new approach can quickly become the center of attention for new applications. Toward this end, the application commonly demands that each user provides a digital identity, a set of bytes that describes that user. As businesses actively pursue efficiency and cost reduction throughout their systems and operational framework, the intrinsic value of a flexible, dynamic, and intuitive computing platform has become significant.The on-premises client is typically a browser or some other simple client. Also the concept of cloud computing significantly changed the traditional approach to the delivery, management and application integration. Tivoli Provisioning Manager uses Websphere Application Server to communicate the provisioning status and availability of resources in the data center, to schedule the provisioning and deprovisioning of resources, and to reserve resources for future use.
Applications that run in the cloud, by contrast, can potentially operate at Internet scale, which requires handling many more simultaneous users than any enterprise application.
Cloud computing involves virtual hosted environments allowing users to connect to the services being hosted over the internet.
EC2 provides customer-specific Linux instances running in virtual machines VMs.
